Radiotherapy Enhancement by Gold Nanocluster‐functionalized Nanoliposomes Using Polychromatic Orthovoltage X‐ray Irradiation

open access: yesAdvanced Materials Interfaces, EarlyView.
Lipid drug carriers to which ultra‐small gold nanoparticles were added enabled more efficient radiotherapy of cultured pancreatic cancer tumors. These nanoparticles boosted radiation‐induced damage to tumors by generating more reactive molecules, though higher gold levels are needed for strong benefits.

Optimal Control of Transient Flow in Natural Gas Networks

open access: yes, 2015
We outline a new control system model for the distributed dynamics of compressible gas flow through large-scale pipeline networks with time-varying injections, withdrawals, and control actions of compressors and regulators. The gas dynamics PDE equations

Effect of Surface‐Lubricant Compatibility on Bubble Formation in Lubricant‐Infused Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Lubricant‐infused surfaces reduce drag partly through bubbles that form when lubricant depletes. Using laser‐textured steel infused with silicone oil, we show that microbubble nucleation occurs even on surfaces fully wetted by the lubricant, regardless of chemistry.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

MACKENZIE VALLEY GAS PIPELINE IN RETROSPECT

open access: yesThe School of Public Policy Publications, 2021
  Canada’s history is punctuated with a number of big and bold national projects, such as the Trans-Canada Highway and the Canadian Pacific Railway, that have played defining roles for the country and its citizens’ prosperity.1 However, over more recent decades, there has been much less success in bringing such projects to fruition. Indeed, the growing

A bridge to a low carbon future? Modelling the long-term global potential of natural gas [PDF]

open access: yes, 2014
This project uses the global TIMES Integrated Assessment Model in UCL (‘TIAM-UCL’) to provide robust quantitative insights into the future of natural gas in the energy system and in particular whether or not gas has the potential to act as a ‘bridge’ to ...

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

open access: yesAdvanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control
